This article analysis the observability question from the localization principle and position error. Based on this, has discussed the question of the multi-baseline phase interferometer direction finding and the phase difference, and proposed an improved fast solution fuzzy algorithm. The simulation result indicated that this algorithm increased the localization tracking accuracy effectively.
This article proposed one kind of new phase difference solution fuzzy algorithm, this method choice base length satisfies certain diverse relations, thus increased the most greatly not fuzzy angle greatly, has solved the direction finding precision and most greatly between not the fuzzy angle contradiction. The simulation result has indicated the theoretical analysis accuracy.
